Read the textbook, don't recite it without thinking, that's called reciting, read the book quietly, close your eyes after reading it, and then remember it bit by bit. If not, read the book again until you can remember it. Remember a little when you sleep at night, remember a little when you wake up in the morning, remember it on the way, and remember it when you eat. If this continues, the results will be hard to say! ! !
